introduction
Copper C110 in CNC Machining
Copper C110, also known as electrolytic tough pitch (ETP) copper, is a commercially pure copper alloy with high thermal and electrical conductivity.
It’s commonly used in components that require efficient electrical transfer, such as electrical connectors and bus bars. It has excellent machinability but tends to work harden, so we do proper cutting techniques, as well as appropriate tool selection, cutting speeds and feeds, and coolants when machining. Copper C110 has good corrosion resistance, although it can tarnish over time. This can be addressed through coatings or finishes if necessary.
With 99.99% copper content and stringent impurity limits, it avoids embrittlement when heated and offers high ductility for easy cold working. Additionally, C110 is easily bendable without breaking; it only requires little force for shaping and stands out for its corrosion resistance. C110 is truly a great option for both indoor and outdoor components. Typically, C110 is available in 1/8 hard (1/8 H) or 1/4 hard (1/4 H) conditions, and it's resistant to annealing.

TECHNOLOGY OVERVIEW
Basic Knowledge of Copper C110
What is Copper C110?
Copper C110, also known as ETP (Electrolytic Tough Pitch), is highly malleable and ductile, with excellent heat and electrical conductivity. Its reddish color is typical for copper alloys.
With a purity of 99.9%, it has 101% IACS conductivity. While not as corrosion-resistant as some copper alloys, C110 copper still exhibits reasonable resistance.

FAQ
Machining Copper C110 Buying FAQ
Yes, C110 copper is oxygen-free. It is classified as electrolytic tough pitch (ETP) copper, indicating high purity and minimal oxygen content.
They refer to different grades or alloys of copper. Copper 101 is oxygen-free electronic copper, while Copper 110 is electrolytic tough-pitch copper.
C102 and C110 are both copper alloys, but their composition differs. C102 has a higher oxygen content than C110.
